Marissa Mayer's Biggest Game Changer Yet

NEW YORK (TheStreet) -- Marissa Mayer has made front-page, bold-type headline news for a whole host of things she has done over the course of her year-plus tenure at Yahoo!(YHOO - Get Report).

Having a baby on the job (not literally). Building a big old nursery. Banning work-from-home. Posing provocatively for a magazine. Hiring David Pogue away from The New York Times. Signing Katie Couric.

All big deals -- no doubt, but quite a bit of sensationalistic media fodder that will have very little, if any, impact on Yahoo!'s business.

News that broke Friday afternoon, which -- relatively speaking -- will fly under the radar, could be a harbinger for one of the biggest game changers we will see from Mayer. Yahoo! made what amounts to another acqui-hire, picking up the team behind live concert streaming platform, Evntlive.

Evntlive was co-founded by former Cisco(CSCO)CTO Judy Estrin, and offered viewers a more immersive live streaming experience of concerts by letting them access multiple camera angles as well as live chats and other interactive features.

Why Does It Matter?

It has become commonplace to refer to live sports as the last bastion of appointment programming in television. Rogers Communications(RCI) and BCE, Inc. (BCE)best illustrate a strategy to lock up sports in Canada. In the States, the major media conglomerates continue to hold the cards even as some viewing moves online thanks, in part, to their foothold on major professional sports contracts.

While not a 100%-parallel example, we can look at music -- particularly live concerts and events such as the American Music Awards or Grammys -- the same way.
